$A$ Zener diode is specified as having a breakdown voltage of $9.1 \;V$,with a maximum power dissipation of $364 \;mW$. What is the maximum current $(mA)$ the diode can handle?

The incorrect statement about the property of a Zener diode is

What is the value of the current $I$ flowing through the Zener diode in the given circuit? (in $mA$)

$A$ $9\,V$ stabilized voltage supply is required to run a car stereo system from the car's $12\,V$ battery. $A$ Zener diode with $V_z = 9\,V$ and $P_{max} = 0.27\,W$ is to be used as the voltage regulator. The load resistance is $450\,\Omega$. The value of the series resistor $R_s$ is....$\Omega$.

$A$ Zener diode with a Zener voltage of $30 \text{ V}$ is connected in a circuit as shown in the figure. The maximum current through the Zener diode is: (in $\text{ mA}$)

$A$ Zener diode, having a breakdown voltage of $15 \text{ V}$, is used in a voltage regulator circuit as shown. The current through the Zener diode is (in $\text{ mA}$)
